Fireball spotted over southern Mississippi, NASA confirms
Friday, 29 April 2022 06:02A loud boom prefaced a streaking fireball spotted in three Southern states, scientists confirmed Thursday.
More than 30 people in Arkansas, Louisiana and Mississippi reported seeing the exceptionally bright meteor in the sky around 8 a.m. Wednesday after hearing loud booms in Claiborne County, Mississippi, and surrounding areas, NASA reported. It was first spotted 54 miles (87 kilometers) above the Mississippi River, near Alcorn, Mississippi, officials said.
"This is one of the nicer events I have seen in the GLM (Geostationary Lightning Mappers) data," said Bill Cooke, lead of NASA's Meteoroid Environments Office at Marshall Space Flight Center in Huntsville, Alabama.
The object, which scientists called a bolide, moved southwest at a speed of 55,000 miles per hour (88,500 kilometers per hour), breaking into pieces as it descended deeper into Earth's atmosphere. It disintegrated about 34 miles (55 kilometers) above a swampy area north of the unincorporated Concordia Parish community of Minorca in Louisiana.
One witness told the Vicksburg Post that she heard a loud noise and then looked up and saw an "orange fireball the size of a basketball, with a white tail behind it," heading west toward the Mississippi River.
The Claiborne County Emergency Management Agency posted a statement on Facebook confirming the reports and noting that Grand Gulf Nuclear Station was not involved.
